Agreed. A 45-year-old HP 4650B with its cavity oscillator has fancier physics going on than you're likely to build at home unless you make building signal generators your hobby for the next decade or two. Just looking into what would be involved in building a stepped attenuator comparable in insertion loss, accuracy, and isolation to the HP-335 series from 1958 should give one pause. The Marconi looks nice. |
